Nuclear Level Transmitter

Would you please tell us the facility you are working at? I am certain there are many people who would like to know this, as action is indicated.

In addition, the 20 PSI is probably insufficient.

Any hazardous system should only be worked on by trained qualified individuals with full documentation of what is at least expected to exist.

YOU CANNOT GET PROPER SAFETY TRAINING HERE!

We can translate a few ideas or concepts that you do not understand. But you and your neighborhood's safety are you and the employers responsibility. Nobody here wants another disaster like Bhopal by Union Carbide.

If you can tell us how this device is used we may be able to guess what it actually is or possibly how hazardous it might be.

From your rambling description though I have no idea what the object is other than it is nothing you should touch.

The instrument has an identity tag on it that includes the manufacturer's name and device's model number.

Find the manufacturer's site on the web and read up on it.

Ronan's nulcear basics are here:

Study the manual carefully. The radioactive source (Cs¹³⁷ would be a typical example) is encased in a lead-lined receptacle with an aperture that allows a narrow beam to "X-ray" the pipe or vessel whose level is being monitored. Before moving this assembly, there is probably a leaded shutter mechanism that closes off the aperture, isolating the source so that it can't be aimed in harmful directions.

If you or your personnel are unfamilar and/or uncomfortable with this, your concerns should be respected. In that case, the instrument maker may have technicians that you can engage for this service. If lead gloves/aprons/etc. are involved, a qualified tech would be the way to go.
